DETACHABLE CALK FOB, HORSESHOES.

To all whom it may concern Be it known that I, THOMAS L. HAIRE, acitizen of the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in Detachable Calks for Horseshoes, of which the followingis a specification.

This invention relates to certain new and useful improvements indetachable calks for horse shoes, and the object of the invention is toprovide simple and improved calks which may be readily and easilyapplied to and removed from the shoe, and further to provide novel meansfor allowing adjustment of the calk sections so as to fit shoes ofvarying widths.

In the drawingsFigure 1 is a perspective view of a horse-shoe with thepresent invention applied thereto. Fig. 2 is a bottom plan view of theinvention in detached position. Fig. 3 is a sectional view taken on theline 3-3 of Fig. 2. Fig. 4 is a perspective view of one of the calksections, and Fig. 5 is a perspective view of the other calk section.

In accordance with the present invention, two substantially-T-shapedcalk sections 1 and 2 are provided, each section having a pair ofoutwardly-projecting calks 3, which latter are arranged at the ends ofthe heads of the Ts. The shank of section 1 is provided with alongitudinal slot 4 and its upper face is provided with an outwardlyextending lug 5 which is adapted to engage the top face of the shoe,which face is nailed to the hoof. The base of each of the ca-lks is cutaway at 6 to form shoulders 7 which permit the calks to conformablyengage the bottom face and inner side of the shoe, as depicted in Fig. 1of the drawings, the shoulders 7 abutting the inner side face of theshoe. The shank of calk section 2 is provided with an upstanding rib 8,which conformably engages in the slot at of section 1. An aperture 9formed in the rib 8 and the shank of calk section 2 receives a bolt 10,the head 11 of which extends or projects over the shank of calk section1 as shown in dotted lines of Fig. 2 of the drawings. It will be evidentthat the bolt 10 will permit of adjustment between the sections,allowing the same to be moved toward or away Specification of LettersPatent.

from each other so as to fit shoes of different widths. The nails 12which secure the horse shoe in position are preferably arranged so thattwo of the same engage on opposite sides of the front calks 3 of thesections 1 and 2 so as to hold the calk sections against movement.

In use the bolt 10 is loosened and the sections contracted relative toeach other and placed within the shoe, after which the sections aremoved outwardly so that the lugs 5 engage the top face of the shoe andthe cut out portions 6 have the walls formed thereby and the shoulders 7engaged with the underface and inner side of the shoe. The bolt is thentightened, and since the rib 8 engages ir the slot 4 lateral movementbetween the shanks of the sections is prevented.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In a horse shoe, a pair of T-shaped sections, the headof each section having a calk at each end thereof, said calks extendingbe yond the outer side faces of the heads and being cutaway on theirupper faces, the vertical walls formed by the cutaway portions being inalinement with said outer side faces of the heads and being adapted tocontact with the inner side faces of the shoe, an outwardly extendinglug on the upper face of each head located centrally of the spacebetween the calks thereof to engage the upper face of the shoe, theshanks of the sections being arranged in overlapping relation, the shankof one section being longitudinally slotted and the shank of the othersection being formed on its upper face with a longitudinal rib that islocated centrally of the space between the sides of the last named shankand which is received in the slot of the first named section, and a boltpassed through said rib and the section carrying the rib and extendingthrough the slot of the other section.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
